| Abstract | ||
| This experiment was conducted to evaluate the effects of different levels of hull less barley with and without enzyme in diet on performance and relative efficiency of energy and protein. The broiler chicks were fed in 5 starter (1-21d) diets containing 10 and 15% hull less barley with and without enzyme and control diet and were fed in 5 grower (22-41d) diets containing 15 and 20% hull less barley with and without enzyme and control diet. These treatments were arranged in a completely randomized design with 4 replicates as each replicate consisting 20 broiler chicks. The performance (body weight gain, feed intake and feed conversion ratio) and relative efficiency of energy and protein calculated via weekly weighing and standard formula. The results were analyzed with SAS program and means compared with Duncan’s multiple test in P<0.05. The results showed that regardless of the level of hull less barley in diets, due to the presence of non-starch polysaccharides in this feed, performance and relative efficiency of energy and protein were reduced. While used of enzyme in the diets can eliminate the negative effects of non-starch polysaccharides on productive parameters. Therefore, the results of this study showed that can be used the high levels of hull less barley in the diets if appropriate with level of hull less barley supply these diets with enzyme. | ||
